Justin Bieber has some pretty die-hard fans, but there are some celebs who just aren’t quite catching on.

So who’s on the list? Well to start: Orlando Bloom. After video surfaced Wednesday of the actor taking a swing at the 20-year-old, it would appear to be as though he’s on it. Joining him, and reportedly cheering him on, is Leonardo DiCaprio. According to sources, the actor witnessed the whole thing and was on team Orlando.

Along with those two hunks is Seth Rogen. The Neighbors actor hasn’t been shy about his dislike for the Biebs. In addition to tweeting back in January, "All jokes aside, Justin Bieber is a piece of sh**." He also went on Howard Stern’s Sirius XM radio show in May to talk about his experiences meeting Justin.

"We were backstage at a German talk show and someone literally came to the door and was like, Justin Bieber wants to meet you," Seth revealed about his first interaction with Justin. "I was like, sure I'll meet him. And then I went outside to meet him and he was acting like I asked to meet him. He was very nonchalant like, 'Yo man, what's up,' and I was like, ‘What the f***, I don’t give a f***, I don’t want to meet you."
